The apparatus may be implemented upon liquid reservoirs exhibiting a risk of the release of an undesirable substance, for example PFAS. The apparatus includes at least one sheet material 2 sized to substantially cover the surface 3 of the liquid reservoir 4. This prevents/minimises the amount of untreated substance that escapes into the atmosphere. A spacer arrangement is disposed at or above the surface 3 of the liquid reservoir 4 to retain the sheet material 2 above the surface, maintaining an interstitial space therebetween. The undesirable substance is captured within the interstitial space by the sheet material 2 until it is subsequently evacuated. The evacuation is done through conduits 7 having a plurality of inlets 8 disposed thereupon that are in fluid communication with the interstitial space.
A method and apparatus for separating an amount of a perfluoroalkyl or polyfluoroalkyl substance (PFAS) from water which is contaminated with the substance includes a method that comprises the steps of: admitting an amount of the water, which includes an initial concentration of the substance, into a chamber via an inlet thereinto, and introducing a flow of gas into the chamber, and the introduced gas induces the water in the chamber to flow and produces a froth layer which is formed at, and which rises above, an interface with the flow of water and of introduced gas in the chamber, the froth layer including an amount of water, and also a concentrated amount of the substance in comparison with its initial concentration, and including the step of removal of at least some of the froth layer from an upper portion of the chamber.
A method and apparatus is disclosed for separating an amount of an amphiphilic contaminant substance such as PFAS from water. The method comprising the steps of admitting the water which contains the substance into a flotation cell chamber, and then introducing a flow of gas thereinto. The gas is introduced by several different apparatus options for efficient aeration of the chamber, depending on the water being treated. The introduced gas produces a froth layer which is formed at, and which rises above, an interface with the contents of the chamber. The froth layer includes an amount of water and also a concentrated amount of the contaminant substance when compared with its initial concentration. The process then involves collapsing and removing the froth layer, with several options for removing the PFAS from that liquid by re-flotation to reconcentrate the PFAS, or absorption onto a solid substrate material. The treated water an also pass out of the chamber through an absorptive treatment device to remove an amount of the substance not already recovered in the foamate.
A method of separating trace amounts of amphiphilic substances from water which is contaminated with the substances, the method comprising the steps of: admitting an amount of the water, which includes an initial concentration of the substances, into a chamber via an inlet thereinto; - introducing a flow of gas into the chamber, wherein said introduced gas induces the water in the chamber to flow, and produces a froth layer which is formed at, and which rises above, an interface with the said flow of - controlling the water content of the froth layer which rises above the interface to influence the concentration of the substances therein; and - removing at least some of the froth layer from an upper portion of the chamber.

Apparatus for separation of a substance from groundwater
Apparatus is disclosed for separating an amount of a substance from groundwater, comprising an elongate chamber (18) having an inlet (22) which is arranged in use to admit groundwater into the chamber near a lower first end (24). There is also a gas sparger (26) located near the first end (24) which admits gas into the chamber for inducing groundwater to flow from the first end (24) of the chamber toward a second end upper end, and for producing a froth layer (32) which rises above an interface with the groundwater including a concentrated amount of the substance. A suction hood (38) can be moved downward from the top of the chamber (18) into a position to collapse the froth layer (32) and to cause it to be removed from the well body (14). The suction hood (38) (acting as a froth depth regulation device) controls the amount of groundwater in the froth layer (32), which influences the concentration of the contaminant substance achieved in the froth layer (32).
